This has happened twice in the last two days, since I did the optical drive firmware update, so I haven't been able to collect a huge amount of data about it, but it's weird enough (and happened twice, not once) so I figured I'd ping to see if anyone else has seen or heard about a similar problem (a quick perusal of Google and Apple Support finds nothing apropos).

The symptom:
Wifi is working fine. Suddenly I lose the connection with no warning or error, it just drops. When I go to reconnect, it fails ("There was an error joining that network"). Weirder still, when I use the Airport Radar widget or just click on the airport menu to see what networks it sees, both are empty. The Airport now sees 0 networks! This is not a short term problem. This persists until I restart or sleep it for a long time (presumably long enough that something resets in the Airport card/driver). Turning off and on the Airport (as a network) does nothing.

This is also provably not a wifi problem, as other people using the network are uninterrupted. And a reboot fixes the problem immediately.

Possible fixes so far:
-Reboot
-Sleeping for a long time

The question:
Am I just crazy? Has anyone else seen it?

Many helpful posts in the networking forum...

Try deleting those favorites and then re-establish them.

Try simply turning your AirPort card off and then on again (through the AirPort thingie at the top of the screen). Wait a bit, maybe 30 seconds, between off and on. That should do it.

The Draft N "standard" is still a draft-for good reason in some cases. You can expect a few oopses when using "not yet fully standardized" equipment.

I have the same problem on my 2.4 MBP where I lose connectiona nd I also cannot see any other networks even if I do know there are about 10 Wifi networks in my area.

so even if I am using G speeds I am still technically using the N functionality?

Using ANY part of a device that is built to the draft N standard means that there's a possibility that something will bork out on you. The software that runs the device is not like a bolt or hinge-it's really complex, and there is a LOT of complexity in the draft N standard. So code that makes the draft work ok may just hose up the G side from time to time.
